479513 divided by 20 
We want to figure out the number of times 479513 can be divided by 20.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 20

Step 2:
20 goes into 47 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 40 from 47 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 20

Step 3:
20 can be fit into 79 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 60 away from 79, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

Moving on to step 4:
195 divided by 20 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 239.0
Subtracting 180 from 195 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 20

On to step 5:
When dividing 151 by 20, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 2397.0
Deduct 140 from 151 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 20

Moving on to step 6:
If we divide 113 by 20, we get 5 and a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 23975.0
If we take 100 away from 113, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 20, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 23975.6
Subtract 120 from 130 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 23975.65
If we subtract 100 from 100, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23975.65
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23975.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 23975.65 with a remaining 0.0.
